Acne Control

Oral antibiotics are so effective at treating acne that many patients are reluctant to stop taking them for fear of flare-ups. But new research shows that three months of antibiotics may be sufficient. After that, topical retinoid gels alone, such as Tazorac or Differin, may keep acne in check just as effectively as continued antibiotics. Prolonged use of antibiotics can backfire by leading to antibiotic resistance, says Diane Thiboutot, professor of dermatology at Pennsylvania State University. Side effects of retinoids include mild irritation, dryness, and sun sensitivity, she adds.
